Rory is the beloved mascot of Futura OS โ a self-contained serpent that feeds back into itself, eternally consuming and renewing. With pastel coloring and circuit-board patterns woven throughout her form, Rory embodies the kernel's capability-based design philosophy.
Like the ancient ouroboros symbol from mythology, Rory represents the eternal cycle of system evolution and self-improvement. She's a reminder that the best systems are those that can learn from themselves, improve their own foundations, and grow stronger with each iteration.
